word processor

A program used to create and print (chiefly
textual) documents that might otherwise be prepared on a
typewriter. The key advantage of word processor is its
ability to make changes easily, such as correcting spelling,
changing margins, or adding, deleting, and relocating entire
blocks of text. Once created, the document can be printed
quickly and accurately and saved for later modifications.

Today most popular word processors, such as Microsoft Word,
offer a much greater range of facilities than the first such
programs.
